Why did the bear cross the road? To eat Mommy's rhubarb cake.....so said my son. This is an easy coffee cake that you will want to let cool completely before cutting into. If you like it more tart, or more sweet, just adjust the sugar amount to your liking. You may use Splenda in the place of sugar. I used my hands to mix up the crust as it makes quite a thick dough. Timing does not include cooling period.
